Electron-Phonon Coupling in Two-Dimensional Silicene and Germanene

Following the work in graphene, we report a first-principles study of electron-phonon coupling (EPC) in low-buckled (LB) monolayer silicene and germanene. Despite of the similar honeycomb atomic arrangement and linear band dispersion, the EPC matrix-element squares of the \(\Gamma\)-\(E_g\) and K-\(...
